About drawing a vehicle trajectory diagram

[xql5891129]

Add your issue description here.

If possible, upload an example that shows your problem. I now have some GPS data for the bus, which contains the route number, latitude and longitude of the bus. I found that the road network exported by osmWebWizard has latitude and longitude information. Is there any way to draw a trajectory map in the road network based on the GPS information of the bus?I want to see which intersections the bus has passed. thank you!

You could convert your input data to SUMO polygon format using polyconvert and load it in your network as an additional file. Probably you have to use an intermediate format like shapefile or navteq to get it working.

I use “net.getNeighboringEdges(x,y)” to find the edge closest to my latitude and longitude coordinates, but the return value is always empty

[namdre]

call net.convertLonLat2XY first to get x,y coordinates for getNeighboringEdges.

首先调用 net.convertLonLat2XY 以获取 getNeighboringEdges 的 x，y 坐标。

Thanks, I found the reason, I should turn up the argument “r” in function “getNeighboringEdges” a bit more

[xql5891129]

I can now use the function getNeighboringEdges to get the road IDs by combining the latitude and longitude coordinates of the bus, but I have a problem merging these road IDs into a route. I need to determine if there is a connection between the two road IDs, is there such a function

Thank you for your help, but when I use tool ‘tracemapper.py’, I generate a route file with some edges that are not connected.Is there any way to fix it

[namdre]

run with with option --fill-gaps (set the maximum possible gap size you wish to close).

[xql5891129]

But no matter how I tweak ‘--fill-gaps’ , there is nothing in the generated rou file

Can you share your inputs? And maybe @behrisch has more indeas on this?

Can you share your inputs? And maybe @behrisch has more indeas on this? The ‘tracemapper.py’ is in my python file ‘csv2rou.py’, and '506_2023-01-01.csv' is the GPS data of my bus.Thank you for your help caijia.zip

The data is too noisy to for mapping to the correct edge and possibly the network geometry is inaccurate in some places as well. As a further problem the density of points in time is either very low or the data points are in the wrong order. The screenshots shows some data points along with their index of occurrence. As you can see there are hug jumps in index which either means the trace contains many loops and is also sparse or the points are out of order.
